Title: Ranging system and method for satellites
Inventor: SIEBERT PETER
IPC: G01S13/32
Filed: 2000-02-08
Abstract: In a satellite ranging system predetermined bit sequence or group of bit sequence in a transport stream, which is a digital signal, are used to generate trigger signals on the basis of which the delay introduced into the transport stream by the travel path from a satellite ground station to the satellite and back or to another satellite ground station is determined allowing a calculation of the distance between the ground station(s) and the satellite.

Patent CA-2413185-A1 (CA)
Inventor: SOANE DAVID S
IPC: C08F2/48
Filed: 2001-06-13
Abstract: This invention is directed to a process for the rapid in-situ curing of polymerizable materials to provide macromolecular networks and articles of manufacture that are "morphology-trapped"; that is, they exhibit a fixed phase morphology and/or molecular orientation that is locked in by the curing step.  The process includes the steps of mixing together a dead polymer or a prepolymer, a reactive plasticizer or a diulent, and an initiator to give a polymerizable composition; further processing the mixture in order to achieve a desired phase morphology and/or moelcular orientation of the polymeric constitutents; shaping the polymerizable composition into a desired geometry;  and exposing the polymerizable composition to a source of polymerizing energy, without mixing, to give a final product with the desired phase morphology and/or moelcular orientation locked in place. The phase morphlogy and molecular orientation present just prior to cure of the polymerizable composition is subsequently trapped or locked in place by the curing step to that further changes in morphology are hindered or prevented.
